The ThunderJet 185 Explorer 2013 is a deep-V design and the ThunderJet Bulldog 2009 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The ThunderJet 185 Explorer 2013 measures 20,4 feet overall (2013), giving it roughly 3,4 additional feet of deck space compared to the ThunderJet Bulldog 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the ThunderJet Bulldog 2009 tips the scales at 2 500 lbs - 1 200 lbs less than the ThunderJet 185 Explorer 2013 at 1 300 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 200 hp, the ThunderJet Bulldog 2009 has a 50-hp advantage over the ThunderJet 185 Explorer 2013's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the ThunderJet 185 Explorer 2013 carries 48 gallons versus 32 gallons in the ThunderJet Bulldog 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The ThunderJet 185 Explorer 2013 is rated for 6 passengers, while the ThunderJet Bulldog 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet 185 Explorer 2013 could be the deciding factor.
